When it is essential to have high performance in your application, these low noise drivers offer excellent current stability in Constant Current mode or < 0.02% power stability in Constant Power mode. Precisely control the laser diode or photodiode setpoint current with the onboard output current adjust trimpot or via a remote voltage to the modulation input. Adjust the limit current trimpot to protect the laser diode from exceeding its maximum current rating even when modulating your laser diode. Measure laser diode and photodiode current from two buffered monitor outputs. An evaluation board (P/N: LDDEVALP) and cable (P/N: WCB201) are available to speed implementation of the LDD in your application. For 400 mA, the LDD400 Series is available.

Very low leakage current (15 µA) makes it ideal for driving most VCSELs using the remote modulation setpoint input. It operates from 5 to 12 V. Just add an external power supply and your laser diode to this simple 8-pin controller.

The LDD200-1P drives Type A & B laser diodes with a photodiode range of 15-2500 µA.
The LDD200-3P drives Type A & B laser diodes with a photodiode range of 5-125 µA.
The LDD200-2P drives Type C laser diodes with a photodiode range of 15-2500 µA.

The LDD200 is excellent for laser spectroscopy, electro-optical systems, and contamination control devices.

Free, effective, and responsive technical support is available to simplify integration of Wavelength products into your OEM design. Standard product can be easily modified to meet your application requirements.
